O. ALL WHOM I'l MAY CON CERN Be it known that I, ISAAC RORABACK, of South Bend, in the 'county of St. Joseph, and'St/ateof Indiana, i

have invented certain new and useful Improvements in Harness-Buckles; and I do rhereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a plane view.

Figure 2 is a side view.

Figure 3, a longitudinal section.

Like letters of reference refer to like parts in the different views presented. v

I In the drawing, Arepresents the hamestug, B the trace, and C the clasp or buckle. This buckle consists of the two sides, D, in which is eut a slot, E. These sides are Vconnected to each other by cross-plates F F', iig..3, the purpose of which will hereinafter be shown. y Y

G is the tongue of the buckle, and is secured between` the sides D by a roller, II, which allows the tongue to move freely in the direc-tion of the dotted line-a, and backward and forward between tho-sides,'thc ends of the roller moving along in the slots.

The practical use of this clampis as follows, viz

The hauies-tug is secured to the cross-plates F by being lapped around it, as shown in iig. 3, then returned, and being sewn down, and further securedby the rivet c.

The trace is attached by'inserting the end through the loop b, iig. 2, at thc ond ofthc buckle. From thence it is passed along under the tongue, and confined in the loop I,nnd thus secured from pullingout by the tongue being pressed down, as sho'wn in iig. 3. d

A pin, J, projecting from the under side of the tongue, enters a hole in thotraee, which, on the trace beingl pulled back, draws the tongue also back,` thereby depressing the confined cud down upon the trace, in conseq'uence of' the downward inclination of the slot, which forms an inclined plane, on which .the roller uiovcs'back, thereby pressing hard down upon the trace and upon the hainesftug. The tug, as will be seen, is. swelled upward by the introduction of filling C upon the cross-plate F, thereby making an inclined plane in the opposite direc` tion of that in the slot. Hence, as the roller moves back and` downward in the slot, depressingthe trace down upon the tug, it is resisted by the upward inclination of thetug, the result of which is te clamp the tug and trace firmly together, so that the stronger the draught exerted upon the trace, the tighter will the trace and tug be clamped together. l i Y The trace can be shortened up or lengtheued' out by shifting `the pin Jufrom one hole tonnother, in either direction, asv the case may require. This pin, it will be seen, penetrates' the truce, and enters the tug in a" slot, a,"`which allows the trace to move in'either direction, for a short distance, so as to bring the trace within the action of the inclined plane of the slot E.

This clamp, in practical use, is far superior to the ordinary buckle, for the reason thattheitrace is not subjected to any cramping or short bends. The trace being nearly straight, hence will wear muchlongcr than the trace confined in the common buckle. It is also much more easily manipulated than the buckle in ordinary use.

What I claim ns my improvement, and desire to secure by Letters Patent, 1s--f The sides D, provided with inclined slots E, cross-plate F, and filling C, as arranged in combination withthe tongue Gr and roller H, in the manner as and for the purpose specitied,as a new article of manufacture.
